Many ancient samples from Arabia are on the way. Some from the Neolithic and others from Bronze and Iron Age. One of them contains a Bronze Age T1 from Khaibar.
The theory of T1 expanding from the Fertile Crescent together with J1 into Arabia while others went from the Fertile Crescent into Europe seems to get stronger and stronger.
Come on man you know that bronze age lineage aint gonna be related to us. Check out T-CTS11451, you'll see tons of arabs on their. if a deep subclade is found in that sample you know its gonna be under that.
It originating from the fertile crescent doesnt mean that it had to go through the arabian peninsula into HOA. And even if it did, why don't we see alot of samples along the migratory path? The arabian peninsula is oversampled and even if it did venture their in low frequency, just by the tribal nature of arabs, some tribes will go through founder effects. Also that region never went through massive population change, the relative population group is static, so why aren't the descendents of the sabaeans, himyars, hadramis, adnanis positive for T-Y45591?
